Patented Feb. 4, 1908.

To all whom it may concern:V

Be it known that I, HERBERT H. STEELE, citizen of the United States, andresident of Syracuse, in the county of Onondaga and State of New York,have invented certain new and useful Improvements in Type- WritingMachines, of which the following is a specification. y

My invention `relates to ribbon mechanism for typewriting machines andin general terms has for its Object to provide means for changing orshifting automatically at a predetermined point or lpoints in the lineof writing from one character to another of rinting or of inking meanshaving a'pl rality vof characteristics, or more specifi ally from onefield to another of a ribbon having a plurality of fields of differentcharacteristics.

To the above and other ends the invention consists in the features ofconstruction, combinations of devices 'and arrangements of artshereinafter fullyA described and particuarly pointed out in the claims.

I have shown my invention as applied to a N o. 3 Monarch front-striketypewriting machine, which machine employs a vibratory ribbon carriernormally maintaining the ribbon away from the printing point; but it isto be understood that the invention is applicable to other forms ofwriting machines and that in its broader aspects said invention may beapplied to machines which do not employ av vibratory ribbon carrier aswell as to machines of the Monarch style'or In carrying out my inventionin the present instance two or more coperating shiftv'the action of thetypes, may be changed automatically at one or another of a luralityoffpredetermined points in the ine of writing. My ribbon` field-changingimprovements are preferablymadeuse of in connection with tabulatingdevices, the tabulating de-4 vieeseemployed in the present instancecomprising coperatingstops which arrest the carriage inpredeterminedcolumnar positions whenl it is released from its step-bystep feedingmechanism. Preferably l employ certain of said tabulating stops as oneor more of the shifting members before referred to, the parts soco-aoting that if, for example, a ytwo-color ribbon be used, thevcharacters inone column on the work sheet may be Written in one colorwhile the characters in an adjacent column may bewritten in Vanothercolor, thereby obtaining results which are particularly useful andoonvenient in various forms of commerical typewriting.

In the accompanying drawings, Figure 1 is a full-sized longitudinal'vertical sectional view of a typewriting machine embodying my invention,parts of the machine being omitted'and parts being broken away. Fig.- 2is afull-sized fragmentary rear elevation showing the upper part of themachine, parts being omitted 'and parts 'being broken away. Fig. 3 is atop plan view of some of the parts shown in Fig. 2. Fig. 4 is afragmentary front elevation of part of the mechanism for feeding theIribbon longitudinally.

Two forms of my invention are shown in the present application. Thefirst form, illustrated in Figs. 1 to 9, inclusive, will now 'bedescribed. As shown in Figs. 1 and 2 the main 'frame of the machinecomprises a base 1, cornerv posts 2, of whichl only one is shown, and aKey levers 4 are -fulcrumed on a f u crum plate 5 mounted in the rear ofthe base, each ofsaid key levers being provided 'with a restoring spring'6. Pivoted at 7 to each key lever is a sub-lever 8 which is slotted atits abutment 9 supported at the sides Iofthe base.A iThe upper end ofeach sub-lever. is connected by a link 10-with a type bar 11, said typebar-being pivotally mounted in a hanger 12 secured by a screw 13 to asegmental hanger support 14. The hangers are arranged in arcs of circleson the support and vthe free ends of the type bars 1 1 are normallysupported on.,a type rest 15, said type bars, When actuated, coperatingwith the frontv face of a rotary platen 1Q mounted in a U- shaped platenframe or arriage composed of side-bars 17 anda rear-bar 18 connectingsaid sidebars.v The rear bar 18 is provided at its top and bottom .withop ositely disposed co'perate with antl-friction balls 19, said ballsalso coperating with fixed grooved' rails or track-ways 2() secured byscrews 21 to rearwardly curvedA standards 22 rising from the to plate 3.I-Iorizontally disposed andp. rearwardly projecting arms 2-3 are pivotedat 24 in side 'and 49 (Figs. l1 and .4), the` inions 48 being bars 17 ofthe carriage, said a'rms 23 sup'- porting Iat their rear ends a carriagerack 25 which normally meshes with afeed pinion 26 secured to a shaft26a '(Figs. 2 and 3) journaled on a bracket 27 rising from the topplate. A toothed esca'pement wheel 28 is operatively connected with theshaft 269L and coperative with said escapement Wheel .are

.said frame comprising a rock' shaft 34 'journaled at the sides of thebase and a universal bar proper 35 extending froml side to side of themachine beneath the series of keylevers 4. The universal bar is adaptedto be operated when any of the key levers is actuated,

thereby causing the dog rocker to be vibrated and the d00's'29 tocooperate in a-known manner with the escapement wheel 28 to permit thecarriage to be drawn a letter space distance at a time leftward acrossthe tdp plate under the influence of a spring drum 36' with' which saidcarriage is connected by a band orstrap 37. Q A

Ribbon spools 38 (only one of ywhich appears in the drawings) arearranged above the top plate, one at each 'side of the machine andforwardly of the platen. A ribbon 39 iswound u on the ribbon spools,said ribbon as'herein s iown being divided longitudinally into fieldsuandl b of vdifferent characteristics7 that is to ,sayfthevr field a. or

Vthe lower field may be of one color such asblack and the field b or uper field of a different color such as red, or the field c' may becopyingribbon and the field b record ribbon, for example. The ribbon 39'may be fedk longitudinally from either spool to the other by anysuitable means, that shown in the drawings being substantially the sameas the. ribbon feeding mechanism employed in the Monarch machine. Eachribbon spool 39 is carriedbyan upright shaft 40 (Fig. l.) which rotatesin a fixed bearing 41 and has secured to its lower end a smallV beveledgear 42. The gear 42 meshes with abeveled'pinion 43 secured to theforward end 'o'fva horizontal shaft'44 which shaft carries -at its rearend a y beveled pinion 45, said pinion 45 being adapted to mesh with abeveled'driving pinion 46 (Figs. 2 and 4) mounted on a `driving orpowerv shaft 47. Rotarymovment is trans-' mitted to the shaft 47 bybeveled pinions 48 operatively-connected with t 1e driving shaft and thepinion 49 with the .s ring drum.'36'.. It will be understood that bot-ribbons ools lare providedwith like gear trains whic fare adapted tobe'actuated.bydrivingpinions'46 13o on theshaft 47. Said shaft isjournaled in `lugs 50 depending from the under side of the Midway.between the ribbon spools the ribbon 39, as best shown in Figs. 1' and8 is threaded through a vibratory ribbon carrier or vibrator 51, saidvibrator being guided and supported in the upright arms 52 of a guidebracket 53, the latter being suitably secured tothe top plate of themachine. The stem 54 of the carrier or vibrator is formed with a slot55, therebyT providing arms 56 which carry a cross pin 5,7, said crosspin Vbeing engaged by the slotted forward Aend of an operating member orlever 58 which has a pivot or fulcrum in 59 j ournaled in the arms 60 ofa U-shaped) bracket 61den pending from the under side .of the top plateand secured thereto in a fixed relation by a headed screw 62.

vAs will be seen the operating lever 58 is pivoted about midway betweenits ends, thus providing a two armed lever. The free end of the forwardarm of said lever is ivotally connected with the vibrator 51 an end ofthe rear arm of said lever is curled or turned back on itself asindicated at 63 to provide an opening the interior of which is threadedand receives an adjustable screw stop 64, which, during the operation ofthe machine, cooperates with a stop member presently -to be described toeffect a positive stoppage of the operating lever 58, the screw stop 64being made adjustable so that the coperation between it and said stopmember may be properly timed. lAs shown in Fig. 9 limiting collars orsleeves 65 and 66 surround the pivot pin 59 of the operating leverbetween the arms 60 and serve to prevent lateral movement of said levertowards one or another of said arms. lThe collar 6'5 is comparativelynarrow and the collar 66 comparatively wide, the latter being' at theleft of an operating llever and serving to main.

extending laterally from the upper end por-l` tion of a connecting link69, the lower end of the latter being pivotally connected at with thearm 33 of the universal bar frame, a yielding' or swinging connectionbeing thus .provided between the connecting link 69 and the free theoperating lever 58. A. pin 71, best shown in Fig. 9, projects laterallyleftward from the rear arm of the operating lever in position tocooperate with the rear portion of the spring 67 to prevent the latterfrom uncoiling and to limit the upward movement of theflink 69 r4'underthe influence of said spring 67. The pin 71 .enables the spring to havean initial tensionand affords a deiinite relation between the link 69and lever 58 in normal position. The construction, it will beunderstood, is such that when a key lever or the spacing levers (notshown) are operated the link 69 will be drawn downward vand through thespring 67 will actuate the operating lever 58, causing the forward armof the lever to swing upward and the rear l arm of the levei1 to swingdownward.

The`

normal position of the vibrator is such that theribbon is normallymaintained below the printing point, but when the operating lever isactuated the vibrator will be thrown upward to interpose the ribbonbetween the types on the actuated type barand the front face of theplaten.

When a ribbon like 39 having longitudinal fields or stripes of differentcharacteristics or colors is em loyed in a machine having a vibratorribgon carrier it is necessar to vary the t row of the carrier in orderto firing one field or another of the ribbon to the printing point. Inthe present instance I prefer to effect this result by providing a stopmember adjustable to coperate with the stop 64 to arrest the operatinglever 58 vat different points in its travel from a single normalposition. It is to beunderstood, however, that this is only one wayof'e'ffccting thechange or shift in the ribbon field and that variousother ways of accomplishing this result may be used within the broaderaspects of my invention. The stop member or ribbon field-changer hereinillustrated is clearly shown in Figs. 1, 2 and 5 and is designated as 'awhole by the numeral 72. Said stop member is in the form of afsleevewhich is mounted on the ribbon driving shaft 47 and comprises acylindrical stopping portion 73 of comparatively small diameter, alarger cylindrical stopping -portion 74 joined to the portion 73 by aconed part 73, a hub portion '75 adjoining the stopping ortion 73 and asecond hub portion -7 6 at the left of the cylindrical stopping portionthe inner end whereof engages with a slot 7 8 -formed in and extendinglongitudinally of the drivingvshaft 47, the construction being such thattheA stop member 72 may be moved lengthwise of said driving shaft andrelatively -thereto but is caused tol turn with said shaft when thelatter is rotated. it will be ap? parent that by moving the stop member72 lengthwise of the driving shaft one or an` other ofthe stoppingportions 73 and 7 4 will ioo . sto ping portion l74 be brought intoposition to coperate with construction is such and the parts aresoproportioned that when the operating lever isv arrested bythe stopportion 73 the ribbonwi-ll have been lifted far enough to bring thebottom field or stripe a to the printing point While ifi the stop.portion 7'4.is operative the operating lever will be arrested by thelarger and the ribbon will not be ifted so high but will be thrown onlyfar enough to bring the upper field or stripe b into the path of thetypes.

Briefly expressed, one ofthe 4chief ends sought by my present inventionis tov-effect an automatic change or shift from one ribbon field orstripe to another, whether these ribon fields are on the same or'o'nseparate ribbons, or' from one means, or'one character of printing, to.an-v other -at a predetermined point-orlpoints in the travel of thecarriage or in the line of writing. In they present instance I effectthis object by providing devices which operateto shift .the stopmember72 lengthwise ofthe driving shaft tov bring one lor another of fthe stopportions 73 into operative position, said devices being automaticallyactuatedy by adjustable devices carried by the`- traveling element orcarriage of the machine.

- As the invention -is shown carried out inthe present case, it will be,noted that when the automatically operating shifting devices operateduring the actuation of the tabulating devices or of thel printing keysthe ribbon is v not bodily or physically shifted simultaneously therebyto change from `one field to another, but that by said shifting oeration" provision is made for va different t row of the ribbon whensubsequently a writing key is struck. Thus in substance and effect theribbon is shifted or changed by said shifting devices .to cause avchauve of field, thisvchange or shift from one ribbon field yto anothertaking;place automatically during the oper-- ation of. the machine. But`I do not intend "lmy generic claims to be ih'terpreted to cover "onl amechanism of the specific type in which I have herein shown my inventionembodied. VThe automa'tic shifting means f for the' stop member'72,compr'ises a vertically disposed arm 79 bifurcated at its lower end,thearms 80 of thelbifurcation extending into a circumferential grooveorde ressionl 81 formed in the hub-portion 76 o the stop member 72 asshown in Figs. `1, 2 and 5j The up v with a col ar 82 formedwith'acentral open- -ing which receives'thefliner end of aslide rod 8 3, saidarm 79 beiitgfheldin` a fixed relation with the slide rod.. by a setscrew 84 which passesythrough the collar portion 82 and abuts againstsaid sliderod. Saidslide rod haslits' bearings in the ,right-hand lug'50? character of inking y of the 'ournaled and in a-smaller lug-85depending roml the underl side of the top plate at the left oftheright-hand lug 50.

'As will be seen from anvinspection of' Fig. 2

the slide rod 83 extends from near the middle of the machinehorizontally towards the right, and near its right-hand end portion saidslide rod has a collar 86v secured to it by-a set screw 87, said Fig'.2, it will be recalled, being a rear view. The to of the collar isformed with two' V-sha e depressions or notches 88and 89. -operativewith said 'notches is a roller mounted at the free end of the spring arm..91 which is secured by a headed screw 92 to 'a lug 93 depending fromthe top late. .The

pair in which the-4 driving shaft 47 is detent construction is such thatwhen t e slide rodv is shifted lengthwise to and fro as presently to bedescribed, it will be maintained against accidental dis lacement ineither of the positions toy which) operation between the detent 90 andone or anotherof the notches 88 and 89.'

y Vc'ollar94 is mounted on the slide rod 83 between its bearing lugs,'said .collar being secured in a fixed relation with said slide rod by aset screw 95.l Projecting hori of the collar 94 is a vposed rock shaft100, said rock shaft being 1Journaled in' the depending 'armsV 101 of' aU-shaped bracket 102 which is secured by headed screws 103k to the underside of the top plate. A crank arm 104 is provided at it may be moved bythe co4' ioo its lower end with' a collar Vportion 10'5 which 'A 'isperforated -to receive the rear end portion of a rock4 shaft. 100.

portion yof lthe crank `arn1. 104 is pivotally connected by a looserivet 108 with one end y kofa link 109y arranged horizontally above thetop plate andconnected atj its other end by` iis The upper end a looserivet 110 with a shifting member or lever 111 which is pivoted on aheaded shouldered screw 112. The end of said shouldered screw is reducedand threaded and engages in a tapped hole in the cross plate 113 ofa'VU-shaped supporting bracket,

a nut 114 (Fig. 1) engagingl with the forward end of the reduced portionof the screw 112 at the opposite Iside of the plate-like portion 113 andserving to secure said screw in a fixed relation with said plate. Itwill be seen that the lever-111 is confined between the rear face of thepart 113 and the under side of the head of the screw 112 so that saidlever may turn freely on said; screw but is held from movement axiallythereof.. The

^ U-shaped bracket in addition to thev platelike portion 113 comprisescurved side arms 115 (Figs. 1, 2 and 3) rojecting forwardly anddownwardly from t e ends of the platelike portion 113, said armsterminating in angularly disposed tabs or ears 116 which are perforatedto receive headed screws 1'17,

` said screwsl entering tapped holes in the lower guiderail 20 andserving to maintain the U-shaped bracket in a fixed relation with 'saidguide rail.

. It will be noted from an inspection of Figs. 2 and '3 that by theconstruction described the shifting memberor lever 111 is mounted on afixed part of the/machine somewhat to the right of themiddle thereof.The upper end .portion of said lever 111 is provided with'- extensionsor lugs 118 and 119 having inner oppositely disposed contact faces whichare in planes radial of the center about which the lever 111 turns, saidcenter being the axis `of thc shouldered screw 112. Said lugs orextensions 118 and 119 are spaced apart as clearly appears in Figs. 2and 5to permit ofthe coperation of either one of them,

without interference by the other, with one or more cooperatingshiftingor contact members mounted on the carriage.

Before entering into a detailed description of the shifting or contactmembers carried by the carriage,`it may be well to state that althoughthe carriage may be moved in printing direction either by hand' or aletter space distance at a time under.l the control of the step-by-stepfeeding mechanism, to

bring about acoperationbetween the shifting member on the frame and oneor another' of the shiftlng members on the carriage, yet .I I prefer toemploy tabulating devices to cause movements of the carriage when it isdesired to shift automatically from'one ribbon field toanother or, inother words, to change the character of inkine' means, as such automaticshifting is preferably used in statement, manifest or other tabularwork'and workof this character is facilitated by the use of tabulatingmechanism. The tabulatingmechanismshown in' the-present case issubstantially the same as that employed in riage near the ends thereof.

the No. 3 Monarch typewriter and forming.

the subject-matter of a pending 'ap lication of Jacob Felbel, SerialNo'. 270527, led July' 20, 1905'. Said tabulating mechanism com` prisesa plurality of stops, commonly called column stops, which are mounted onthe carriage and which cooperate with a plurality y `of vstops commonlycalled denomlnational -stops mounted onthe frame of the machine.

In the form of my invention now under consideration I prefer to slightlymodify one or.

Imore of said column stops and to make use of them as shifting membersto coperate with the shifting member or lever 111 on the frame to effectan automatic shift of the ribbonv fields As is -well understood, thecolumn stops, presently tobe described in detail, are adjustable toassist in defining columnar fields;

and it will be apparent from what has been said that when one or anothero f the modified orspecial column stops which I prefer to employ isadjusted, it not only assists to define `a columnar field but alsoloperates to effect `an automatic shifting or changing of the ribbonfields so that the printing in the defined columnar field will be in adifferent color from the writing which has immediately preceded. This Iconsider a valuable feature of my invention, since by a singleadjustment of one of the combined column stop and shifting membersl amnot only enabled to select a columnar field at any The tabulatingmechanism above referredto will be described briefly and'only so far asis necessary to an understanding of its o eration in .connection withthe automatic ribbon field-changing or shifting devices with which thepresent application is more es-l pecially concerned.

Referring to Figs. 1 to 3 inclusive and 5, brackets are secured byheaded screws l 121 at the back 0f the rear bar' 18 ofthe car- Saidbrackets 120 are formed with rearwardly extending arms 122 whichI areperforated toreceive the lend portions of a rectangular column stop bar123 provided at its front and rear sides with oppositely disposed teeth124. Theend portions` 125 of the column stop bar are cylindrical -inshape and are threaded to coperate with adjusting and securing nuts 126,two Iof said nuts cooperating with each A io scribed.'

In addition to the column stops 127: are of the usual form, the stop-bar123 is adapted to supporta special stop member' 129. Said ,member isvmade preferably of "15 sheet metal and. generally, resembles the columnstops 127, being adapted' to iit down overrthe stop bar 123 between theteeth 124 thereof and havin a stopping portion 130 l distance below-thebottom face of the stop upper arm of theribbon shifting member or leverin a manner hereinafterdescribed.' It l-will be understood that thespecial. member 129 combines the functionsv of a tabulating stop and ashifting member and that it is adjustable lengthwise ofthe stop'bar1235and .consequently of the carriage'in.whiehsaid stop bar issupported.: Said membervv 129 may be arranged at the right of theordinary column stops 127 asv shown in Fig. 2,y which figure it will berecalled' is a rear view or vmay be arranged intermediate such ordinarycol"- umnl stops.

It will beiunderstood that the ulating keys 149 in the usual manner,said comprising the forked arm7 9, slide rod'83, lever arm 104, link 109and shifting member or lever 111, are in the positions illustrated inFig. 2, it will be apparent that at printing operation the ribbonvibrator 51 and its actuating devices, comprising the operating lever 58and the link 69, Will be moved from the position shown in, Fig. 1 tothose shown in Fig. 6, thereby throwing the ribbon from the normalposition below the printing point up- 'nvard until the 'lield a or blackfield of said /ribbon covers the printing point and is in f position tocooperate with the type bars.

From a consideration of Fig. 6 it will be apparent that the upwardmovement of the ribbon is positively arrested by the engagement of thestop 64 on the operating lever 58 with the stopping portion 73 of thestop member 72. It will alsovbe apparent that after the stoppage orarrest ofthe operating lever 5S, further downward movement of theuniversal bar and the link 69 will be permitted by the spring connection67 between said link and said, operating lever.' Let it be assumed thatthe initial portion of the Afirst line has'. been Written in black withthe resultthat the carriage has been moved some distance from left toright and the member 129 on said c arriage has been brought close to thelug 118 of the ribbonshifting member 111,. -The appropriate tabulatingkey 149 may nowbe operated to project the associate denominational'stopand release the carriage.

In the form of myinvention illustrated in Figs. 10 to 21 and now to be considered, meansare provided for shifting and re-shifting the ribbon fields a pluralityof times at variable predetermined points inthe travel of the carriagein one direction, the ribbon field-changing or shifting means under someconditions being operated during return movements of the carriage andunder other conditions not being so operated; In carrying out thissecond form of my invention I preferably make use of the tabulatingdevicesA described 4in connection with the iirst form illustrated inFigs. 1 to 9 in' this second -form employing a plurality of specialorcontact members similar to the member 129. These s ecialv members coerate with a rotary s iftin member in t efor'm of a two-part toothewheel to givesaid rotary member predetermined amounts of rotarymovement, said rotary member in turn operating on a ribbonfield-changing mechanism substantially resemblin that above described insuch a way that t e ribbon field is shifted en the printinginstrumentalities are operated after eachcoperation between one of thespecial members and said J'otymember during the travel of the car-L r1ain printin direction. ferr-ing to ig. 10, it will be seen that theribbon driving shaft 47 su ports the slidable .stop meinber72 as in them'ember having stopping-portions 73 and 7 4 coperating with the stop 64carried by the vibratory operating lever 58. The stop member 7 2 isshiftable by means of the forked arm 79 secured to the slide rod 83. Inthe present instance, however, the stop member 72 Ais normally springcontrolled. A collar 166 is secured by a set screw-167 to the slide rodnear its'right-hand end and confined between saidcollar and the bearinglug 50' and coiled around the slide rod: 83 is a h elical spring 168,

said spring .acting through the slide rod on the stop member 72 andserving normally to maintain, the stopping portion 73 of the stop memberin osition to coperate with the sto 64 on t e operating lever .58, asshown in igs. 2 and 6. The result is that under normal conditions thelower lor black field a of the ribbon be operative. In the presst` form,said stop.

A- U-shaped bearing bracket, best showninfFig. 13 and comprising a central portion 173 and side arms l174terminating in angularly disposed ears 175, is secured to the lower IXed rail 20 by headed screws/17 6 which pass through perforations inthe' ears 175 and enter threaded openingsF in Said rail 20 (Figs. .10and 14). The state- 'ment hereinbefore made concerning the positioningof the U-shaped-supporting bracket of the first form of my invention ata greater or less distance to one side of the set of denominational stoplevers 132 is to be understood as applying also to the U-shaped bearingbracket j'ust described in connection with the form of'my invention nowunder consideration. An arm 177 projects .downwardly and rearwardly fromone side of the latter U-shapedv bracket, said arm being provided with aguide slot 178 which receives the inner end portion of the slide bar 170and guides and partially sliding movements. f

If preferred,` the pin 4or stud 186 mayhave fixed'in it as' shown in Fig. `20 a line guiding pin 191 whichv extendslengthwise ofthe slot 185 and is .curved in conformity therewith. Thespring 190is coiled around said pin' 191 which serves to guide andcontrol the spring and cause it to cooperate properlywith the stud 186.The o erations whichare' efi'ective to cause are ative v movementbetween the toothedwheel 181 and the disk' 187 and the -purpose thereofwillbe morev clearly understood from adescriptionto be given later..Atthis stage it issuihcientto state that during the movements ofthecarriage in printing direction, the two parts 181 and 187 are maintained.together in the relations shown in Figs. 20, `10 and 17 to 1.9inclusive.

'40 From an inspection of these `figures it will be '1w noted that Whenviewed from the rear, the` four lu sor-abutments 189. are eachpositioned s `ghtly to'one side'of one of the teeth 183 and-that theremaining four -teeth `183 are further away from and alternatebetweenthe lu s 189, said remaining four teeth 183 also a ternating with' theother four teeth N183., Maintained in this relation by the,

yspring 190-during the travel of thero'arriage "v in printingfdirection,the two parts 181 and 187 operate as a single' member, serving vtotransmit motion'to the slide bar 17() from Vthe special shifting membersmounted on the stp bar 123. y I '55 d has been stated the shiftingor'contact members mounted on the stop bar 123 are of likel constructiontothe speclal member 129 y employed with' the first form. Forfacilitating description, however, the shifting '60 'members in the'present form will be given separate numbers, three' of said numbersbeing shown in thejdrawlifn s and indicated' I from left to right1respective y b the numerals '192, 193 yand-"1911; Each o these mem'- l"bers comprises',fajstopping portioncoperative 'with the denominationalstop levers ,132, the stopping portions of said members being numberedrespectively 192W, 1938L and 194". Each of said members is furthermoreprovided with an extension orcontact Cooperative With the teeth 183 ofthe rotary Ishifting member on the frame of the machine to automaticallychangel or alter the working field of the ribbon as presently to bedescribed, said extensions being numberedV respectivelv 1921, 193band194b; AIt is to be l. that between any two of the understood specialmembers', lone o'r more ordinary column stops 127 may be arranged on thevstop bar 123 according-'as one or more adjacent columns are to bewritten in the same color.

Such column stops will cooperate in' the ordinary manner with thedenominational stop levers132- without interfering with the operation ofthe special members such as 192.

Referring now to the operation of the co-4 operating shifting membersand the parts controlled thereby and assuming that the y carriage andtheworksheet have been properly positioned for writing the :lirst lineof the tabular statement or other matter, the first part of said linemay be writtenby actuating the a propriate character key lever4 4 and,ifnee bercertain of the tabulating keys 149 to cause the carriage tovjump or run 'freelyto columnar positions predetermined' bythe*adjustable column stops A127. Durin the' printing and spacing operationsjust re erred to, the stop ing portion 73 oi the stop member 72 wi l be1n positionjto cooperate with the stop l64 on the operating lever 58 topositively arrest the latter when the ribbon vibrator has been thrownupwardto brin the lower or black field a intoprinting position. At thistime the relation between the two-part rotary shifting 'member and theslide .bar which 'said member opcrates, and which in a sense is also ashifting member, will'be the same asthat shown in Fig. 19, although itis to'be understood that l-none of the special stop' members carried'bythe stop bar 123 will have' reached the posi- Y tion of the one shown inFig. 19 andthat said stop member isfor the time being to be disregarded;From an' inspection of Fig. 19 it will be seen that the lug or toe 171on the,

slide bar 17 0 is engaged' with a sidefaceof` one of the lugs 189. onthe rotary member,

and it will also be understood that' the coiled y l120 exerting va forceon the slide bar' 17() whichl spring 168` on the slide bar 83 is at thistime tends to ress it in the direction of the arrow in said *ig 19.lThis spring pressure, kof course, will b e transmitted throughtheengaged lugs 171 and 189 to the rotary shifting' member, .but motionof the latter is prevented by the contact of the otherlside of the'engaged lug 189'with the end of ea spring sto' 195, which stop isformedof iiatfs'pringmeta bent as shown and secured to th'ejguidearm 'isoavales 177 of the U-shaped bearing orsupporting bracket by any suitablemeans, such as a screw 196. lit will be understood that the` free end olthe spring stop arm 195 is adapted to -yield or to bey cammed downwardlytemporarily by the lugs 189 to per' mit the rotary shifting member toturn in one direction, but that the end of the spring stop 195cooperates with the sides of the lugs l189 to prevent turning movementof said member in the opposite direction'.

The item in the column immediately preceding the column in part deiinedby the spe- .cial member 192 having been w'ritten in blackA theappropriate tabulating key 149 is oper' ated to project the associatedenominational stop and release the carriage from its stepby-stepfeeding mechanism. As soon as the carriage is released it will move orjump to the left until it is arrested by the engagement of the sto pingportion 192n of the member-192 Awit 1 the projected denominational stopon the frame. During ythe run or jump of the carriage just referred toand prior to its arrest by the co-acting tabulating stops the extension'192" of the -member 192 will engage with the tooth 183 on thel rotarymember projecting vertically upward into the path of said extension.After the engagementl and during the further run of the carriage priorto its arrest, the rotary shifting mem er will be turned in thedirection of the arrow in Fig. 10 and will, because of Athe engagementof the lower 'lug 189 with the lug or toe 171 on the slide bar 170,force said slide bar leftward. (as viewed from the rear) overcoming thespring 168 which is weaker than the carriage spring.` The turning of therotary member and the consequent leftward movement of the slide Abarwillv continue until the extension 192b forces the tooth 183 with' whichit-is engaged downward 'out ofits path as indicated 1n Fig. 10.

'- The leftward movement-of the slide bar 170.

operates to turn the crank arm.104 to the left as viewed in Fig. 10,.rocking the rock shaft 100 and turning the crank arm 97 to the right.`The crank arm 97 in turn operates to move the slide rod 83longitudinally rightward in its'bearings with the result that the stopmember 72 is slid rightward on the ribbon driving shaft 47. The partsare so proportioned and adjusted that when the amount of rotarymovementor turning ofv the rotary shifting'. member under the iniiuence of theextension -192 ceases, the member 72 will have been slid rightward tothe position shown in Fig. 10, wherein it will be seen the stoppingportion 73 has been moved to inoperative position while the stoppingortion 74 has been brought into the pat l of the stop 64 on the ribbonoperating lever. The parts between the rotary shifting member and thestop ing member 72 will at this time, ofcourse, e in the positions shownthe side and top "bottom of the'slide bar and the to the right-hand sideof the lug or toc 171 en l the slide bar and lthat the. outer lface of s`d lug 189 is now in engagement withthe ed e o'r corner formed by thejunction between of the toe.

It will be understood that during the turning movement of the rotarymember and the sliding movements of the slide bar 170, slide rod 83 andstop member 72, the spring 168 is constantly tending to force' theseparts in vopposite directions from those in which they are moving andthat therefore as soon as the extension 192 moves far enough to theright, as viewed in Fig. 10, to disengage `from the tooth 183, saidspring 168 will restore or force the parts itA controls tothe positionsf from which they started," unless such restoring movement is prevented.From a con.- s'ideration of Fig. 10 it will be seen that the spring168tends to force the slide bar 17() back in the. direction of the arrow onsaid slide bar, but that 'movement of the slide bar is prevented by theengagement of the lug 189 with the corner 'of the lug or toe 171.

The s ring pressure tends to force the slide bar rlghtward between thetop surface of .the top plate 3 and the outer face of the lug 189, butthe vertical' distance between the of the toe 171 is greaterl than thedistance etw'e'en the top late and the vlower portion of the lug 189. T1e resultis that the slide bar will be wedged betweenl the 'lug and thetop` plate and lwill not only be held from movement itself but will hold'or prevent the rotary member from turning backward in a directionopposite to the arrow on said rotary member under the influence of theslide bar 170.v It will be apparent, however, that the rotary member maybe readily turned backward by alforce extraneous of the slide bar. Bythe action and re-action of the rotary member and the slide bar one uponthe other, it will be seen that each assists to hold the other frommovement and consequently the 'stopping portion 74 of thexmember 72 willremain in o erative position, shown in Fig.

10, during, t e writing of the column inthe part defined by the member192, so thatsaid column will be .written .in red.' The entry vin saidcolumn having'been completed, the tabulating devices are again operatedto release theA carriage which will run freely until arrested by the'enga ement of the member 193with the projecte denominational stop.

the run .of 'the carriage' and prior l l `During to its arrest theextension 193b will engage vwith the vertical upwardly. extending-tooth183 on the rotary membenas shown in Fig. 17, vwith the result that'during the initial stage ofthe run ofthe carriageafter such engagement,the rotary member will be of its path. T

turned from the position shown in said Fig.

17 to that shown in Fig. 18. From a conI sideration of the last namedfigure it will be seen that this initial turning movement" of the rotarymember is sui'licient to carry the engaged lug 189 upwardin thedirection of the arrow on the rotary member until sa'id lug passes theedge or corner of the lugl171. This movement of the lug 1,89 releasesthe slide bar so that it is free to move rightward positions shown inFig. 19. From a con-` sideration of this yfigure itwill be seen that thelug 189 which is now engaged is held between the end of the stop 195(which springs back to lace as soon as the lug 189 has passed over it tothe left) and the face of the toe 171 and -that additional rightwardmovement of the slide bar 170 is prevented.

During this' rightwa'rd movement of 'the slide bar stop member 72 willbe restored by the spring 168 to its first position, thereby renderingthe stopping portion -73 again operative and causing the writing in thecolumn in ,part defined by the member I193 to be in black.

From what has thus tar been said it will be ap arent that in the columnor columns prece ing the column inpart defined by the member 192 thewriting was inblack, While for the column defined 1n part by saidmember192 the ribbon lields were automaticall shifted so that the writing wasdone in redy,l and for the succeeding column in part` defined by themember 193 the ribbon elds were automatically re-shifted so that thewriting was again done in black. For the column nextsucceeding thatdened i part by the mein-ber 193 and which next cdlumn, as shownln Fig.10, is in part defined bythe ordinarycolurnn stop 27,. the Writing Willcontinue to be in black since said ordinar column stop has nofefi'ect onthe ribbon field changing devices. .After the Writing of the columndefined-.in part bythe ordinary'stop,

however, and during the runof the carriage to the columnar positionl in'part defined by the member 194, theextension 194b of said membercooperating with thejrotary ribbon shiftingmember onthe frame, will turnsaid member and slide the'slide bar 17 0 from the positions shownv Fig.19 to those shown in bon s -194 will engage with the vertical e partswill now be in the tension 193", however, acting on the'u Fi 10. Theresult will be that the ribbon iie ds will a ain be automaticallyshiftedas previously escribed and the Writing within the column in part definedby the member 194 will be in red. It will, of course, be understood thatat this time while' the rotary shifting member and the devicescontrolled thereby vfor alteri `the ribbon elds will be in the positionsil ustrated in Fi 10, the

special. members`192, 193 and 194 instead of being in the positionsshown in said Fig. 10

will all be at the right ofthe vertical tooth 183 prpgecting upwardlyfrom the rotary ribh'V ting member.

l Assuming that the red column in part de-4 iined by the member 194 bethe last or final column on the. sheet, the platen ma now be line spacedin the usuall manner an the carriage restored by hand from right to leftto begin a new line or series of entries. Duri the initial part of thereturn movement of the carriage the extension 194b of the memberupwardly extending tooth 183 of the rotar member andswill turn said memer in -reverse direction until that lug 189 which atshifting l thebeginning of said reverse turn was in enga ement with the toe 171 of theslide bar, wi have been moved back until its side en. gages with the endof the spring stop 195, as .shown in Fig. 20. The backward turning ofthe lug 189 permits the slide bar to move rightward, in contact with itunder the in' 'jfluence of the spring 168 so that when said lug isarrested by the stop y195 the slide bar 170 will be in engagement withthe opposite side of said lug, as shown in Fig. .20., From an inspectionof said igure it will be apparent that further reverse turning movenientof the rotary member as a whole will vbe prevented by the stop 195.Because of the yielding or spring connection, however, between the'twoparts 181 and 187 of the 'rota memberfthe. carriage is neverthelesspermitted to continue its 'return movement carrying with it the stop bar123v andthe members 194, 193 and 192 which-move in the direction of thearrow in Fig. 20. From an inspection of this iigure it .will be vseenthat through the engagement of thelug 189 with the stop 195, the disk187 and the pin or stud 186 carried thereby will be held from movementduring this continuance of the returning movement of thecarriage."

From .what has been said it will be seenthat by this form of myinvention'l provide means forenabling predeternnned columns to be-Written in predetermined colors and a column or-columns of one color tobe written intermediate columns of-'a different color; forenabling aribbon having fields of different characteristics to be 1 automaticallychanged orshifted so that lduring the timev L the carriage is passingthrough a predetermined columnar iield a new ribbon field .or

It be observed that the positions of the rota/ry memberand the slide bar 17 0 in Fig.

Consequently during the returnmovement of the carriage the eXtension 194:b on the member 194 insteadof cooperating with the upstanding vertical teeth 183 ofthe rotarymember-to turn said member as a whole from a position corres onding toFig. 1() back'to that shown in Fig. 20, will be ineffective to .turn thedisk187, since the toe 171 with the notch' in the lug 189.Consequentlyvthe extension 194b'will operate only to turn the wheel vart181 of the-twopart rotary memberan will effect a relative rotarymovement between the wheel part said disk Will be held by the engagementof 181 and the disk 187 to the extent indicated in- Fig. 22.

Certain of the principles of construction andoperation of themodification shown inFig. 2,2'form part ofthesubject-matter of a com.-

panionapplication iiled herewith and vbearing erial No..332,-951 and areclaimed therein. It will be obvious that `the relation betweentherotaryshiftingmembei. and. the

,slidebar orl shifting member at the ends v and beginnings-of the'lines'of writing may be controlledbyem loying extra members of the4 characterof t e` member 192 and its l fellows andwhich are in addition to lthoseshifting. members whichv have 'the' double function of assisting inshifting or changing I the elds of the ribbon and in defining columnarfields, said eXtra members being employed merely to control therelations between the rotary shifting membenand the slide bar 170 so asto bring desired ribbon fields into operation. l'for example, from whathas just been said it will be understood that instead of employing themeansdescribed in the immediately preceding paragraph for effecting theresults attained thereby, the same result might be effected bydispensing with the notches 197 and arrang' ing a special member of thecharacter of -192 on the stop bar 123m advance of the first stop ormember on said bar vfwhich is used t0 assist in defining a columnarfield. By employing the advance member in the manner just described, thefield changing mechanism will be positioned to cause the writing in thefirst column of the new line to be in red.

As was said in connection with the rst described form'of my presenti'nvention'ity may at times be desirablevv` to write an entire line ofitems or succession of lines in a single color. In order to effect thisresult in the present instance as in the first form, 1 provide means forrendering the automatic ribbon field shifting or changing devicesinoperative and other means manually controlled for rendering lone loranother of the ribbon fields' operative at will. To render the automaticshiftingor field changing devices vinoperative it' is only necessary, asit was in the first lnstance, to remove the various ribbon field'shifting members 192, 193 and 194 from the stop bar 123.," The resultof such removal will be' that thereafter during the to and fro movementsof the carriage', the rotary shifting member on thelframe of the machineWin not be effected ma ai@ ribbon `asia changing "devices operative bysaid rotary member will not`be shifted. v1f at this time the rotarymember and the arts controlled thereby arein the relations s own in Iig. 10 itwill be apparent that the red field of the ribbon will beoperative. Should it be desired to make use of the black field it isonly necessary to turn the rotary shifting member slightly by hand inthe direction of the arrow in rig. 10 to release the slide bar 170' andpermit the coiled spring 168 to slide the stop member 72 leftwar'duntil' the stopping por-l tion 73 thereon is inoperative position.

, It will be understood that the movements of the parts just referred towill operate to position the'rotaryrshiftingmemher with one of its lugs189 ,engaging with'the end of the' stop 195 as shownin-Fig. 19, and thatduringthe subsequentoperation of the machine saidl rotary member willremain quiescent 1n the position` shown in lfig. 19. :I provide meansfor controlling at wi l the ribbon fields whenv the 'rotary A'member islin `the position vaway from the side shown in big. 19 and whilethere-are no shifting members on the stop bar 123, said 'means beingshown in Figs. 10, 11 and 12 and comprising a rod or bar v198 which isscrewedor otherwise secured in the right,-

hand end (or as viewed from the rear as in if ig. 10, the left-hand end)of the slide bar 83,

said rod 198 being of less Adiameter than the slide rod. As seen infig'. 10 the right-hand end portion of the rod 198 extends through an.opening or slot 199 formed in the side plate 200 of the-machine for theassage therethrough of the ribbon driving s aft 47.

Outside of the side plate 200, the end portion 'ofthe rod- 198 hassecured to 1t a knurled 'finger button 201. Normally or when the blackfieldl a of the ribbon is operative. theffinger button l201' stands late200 as -shown in `iEig.l 12 and bythe 4otted lines in llig. 10, itbeingmaintained in this Vositionby the spring 168. v Near the fingerutton 201, the rod 198 is \provided with a circumferential groove'2'02which forms a short reduced section 203. The groove 202 is adapted tocoperate with a key-hole slot 204 formed in a locking plate 205 slidablymounted on the innerface of the side plate 200.

, The locking plate '205 is provided with i Ielon'gated slots 206 whichreceive small headed screws 207, said screws entering tapped ,holes intheinnerface of the side plate 200. The construction is'such that thelocking plate is adapted to slide fore and aft' of the machine on theshanks of the screws 207 to one positionvor another, the under side ofthe heads of said i'screws and-the inner face of the-sideplate 200acting to frictionally retain the plate 205 in desired position. Theforward end portion of the lockingplate 205 is bent laterally outward atright angles forming a handle vor finger piece 208. by which Asaidlocking plate may be manipulatedsaid handle projecting through a cutawayor slot 209 in theside plate 200. Normally or when Vthe blackfield oftheribbon'is f operative, -thefrod 198` passes through the larger end ofthe key hole vslot 204, as shown in Figs.- 11 and 12, the dimensions ofthe larger -end of said slot being such that'the toand fro movements ofthe rod during the operation of the. automatic ribbon shifting orfieldchanging vdevices are not interfered with. When as is vn ow being'considered thev automaticI ribbon field changing or 'shifting ,devicesare inoperative'and it is desired to :use the upper orI red'fiel-d ofthe ribbon, the finger button 201- isypushed inwardly to the lpositionshown in Fig. 10 toy overcome the spring 168 and force the sliderod 83and the stop member 72 leftward as viewed in said figure untilthestopping portion 74 is in op erativeposi'tion. The inward movement ofthe rod 198 brings the circumferential groove 202-into the plane of thelocking plate 205-, so that the operator, still maintaining the tfingerscares reduced part 203 of the rod 198; but'is not so great as thediameter of the rod outside the groove. Consequentlythe finger button201l l spring 168 vto restore the parts to the normal position Willbeovercome bythe engagement ofthe right-hand Wall-of the groove 202 (aslvievved in-Fi 10) with those portions ofthe right-hand. .ajee of thelooking plate' 205 which .are above'and belfortT thenarroyv endv of thekey-hole sl'o't204. It Willbe' apparent,

therefore, that'aslong asthe'loekingplate I acterisvtics, andlongitudinal-rlbbon feeding' remains in its rearmost position,y theslide rod 83 Willbe locked so as to maintain thestopping portionV 7 elof the stop member '72 lin o erative positibnfsoy that. the red field.of t e ribbonfmay4 be used as long as desired. fWhen it is necessary toagain employ the black-field l i the printing instrumentalities,
